This is the future! Along with planting lots of trees.

For the past five years, Adrian Houston has travelled the world photographing trees that hold a special meaning for a diverse cross section of people. "Trees are among the most important organisms on Earth, yet we continue to abuse them. Rainforests once covered 14% of the earth’s land surface; now they cover a mere 6%. In 40 years they could disappear altogether. Such is my concern that I recently decided to give these trees a voice through the art of photography."
